B. The ZJ-I fully automatic shoulder injection machine is a high-tech new type of hose shoulder injection specialized machine equipment independently developed by our company. All actions of this type of shoulder injection machine are controlled by a large PL. C intelligent touch screen for human-machine operation, integrating machine, electricity, and gas. It has the advantages of high production efficiency, low energy consumption, easy practical operation, automatic fault alarm, stable performance, and no three wastes. By using injection, extrusion, and welding methods, plastic shoulders can be injected onto aluminum-plastic composite pipes and plastic pipes. The shoulders produced have no stitching, with a beautiful and stable appearance.

This equipment can be matched with our company's B.GLS-II composite hose making machine for fully automatic pipe making production lines, and can also be matched with other pipe making machines to produce plastic hoses. Compared with the shoulder injection machines used in China today, this equipment has the characteristics of higher material utilization rate and lower labor intensity.

The equipment mainly includes: fully servo operating mechanism, automatic pipe feeding mechanism, quantitative spraying mechanism, mold forming mechanism, demolding and separation mechanism, automatic pipe unloading mechanism, automatic feeding mechanism, etc.

This device has won two patents. namely:

Patent number ZL200420027317.6: Plastic spraying mechanism of shoulder injection machine;

Patent number ZL200420027315.7: Mold flipping locking device for shoulder injection machine.
